The details of theabove device may be moditied in various ways without departing from the main feature of the invention. For instance, the rod h may be connected directly to the lever G, and the spindle of the. wheel F may be acted upon by a strap and weight instead of by a spring, or a coiled spring may act directly upon the spindle without the intervention of a strap; and in. some cases the pin w may act directly upon a lug or'projection on the rod it, instead of through the medium of the-arm K, and where I may allude to the arm K the latter term is to be understood as including any equivalent device whereby the movement of the pin to can be transmitted to the unclutching-gear. Other means than those described may also be employed for gearing the wheel F to the shaft A, bevel-gearing being used instead of the worm and worm-wheel, for instance, and in some machines such a relation.of the wheel F to the shaft A may be permissible that said wheel may be geared directly to the shaft.

As shown in the drawings,theshaftA forms one of a number of feed-rolls, and the device is intended for use in connection with a spinhing-mule or other piece of machinery in which such feed-rolls are employed; but it may be used in connection with any shaft as a stopmotion device therefor.
